Abstract
Se proporciona una herramienta mejorada para la medicion y registro continuo de la densidad en informaciones subterráneas, que es efectiva en pozos entubados o revestidos. La herramienta mejorada utiliza tres detectores: un primer detector (20) para la compensacion fundamental del entubado o revestimiento; un segundo detector (22) para la compensacion fundamental del cemento; y un tercer detector (24) para proporcionar informacion sobre la formacion subterránea. La herramienta comprende mejoras sobre las herramientas para medicion de la densidad de dos detectores, disponibles actualmente, que son normalmente utiles solo en pozos abiertos. Se anticipa que la herramienta provista aquí será util tanto en pozos abiertos como en pozos entubados o cementados.
